I have my environment setup to listen to jetty on port 8888. However, for a limited time, I will have to also listen on 8889.

I though of using named pipes and nc for that:

mkfifo pipe1
/bin/nc -l 8889 0<pipe1 | /bin/nc localhost 8888 1>pipe1

I noticed that the port forwarding will only work for a certain amount of time, returning the prompt after.

Why is it only working for a certain amount of time?

Is there a better port forwarding mechanism I could use? All of this runs on my local machine, between the ports 8888 and 8889.

This is on a Ubuntu 14.04.

An EOF may be killing it. The following may help:

In netcat - keep listening for connection in Debian the asker points out:

"There's -q -1 option to listen forever after EOF appears on stdin".

If you want to try to avoid the EOF try How to prevent terminating command to send EOF to named pipes?
